近年来的大量试验研究说明,水煤浆不仅是一种比块煤层燃和粉煤喷燃更有利于工业炉窑烧用的低污染清洁燃料,而且由于可以象油一样进行贮存、运输、泵送、雾化和燃烧,从而还可比燃用块煤和粉煤节约现场占地和易于实现燃烧及生产过程的自动控制,减轻工人的劳动强度,改善工人的劳动条件,提高产品的质量。预料,在不久的将来水煤浆将成为工业炉窑的重要燃料形式而广为采用。目前,提供工业燃用的商品水煤浆,浓度通常为70%左右,粘度一般在1000～1500CP(室温、剪切速率为100S~(-1)条件下)范围内。试验表明,这种水煤浆虽然很适于长
In recent years, a large number of experimental studies have shown that coal-water slurry is not only a kind of low-pollution clean fuel which is more favorable for the burning of industrial kilns than lump coal-fired and pulverized coal, but also can be stored, transported and pumped as oil Atomization and combustion, so as to save the on-site space more easily than lump coal and pulverized coal and to realize the automatic control of combustion and production process, reduce the labor intensity of workers, improve the working conditions of workers and improve the quality of products. It is expected that CWS will be widely adopted as an important form of fuel for industrial kilns in the near future. At present, the commercial coal-water slurry is supplied in a concentration of about 70% and the viscosity is generally in the range of 1000 to 1500 CP (room temperature and a shear rate of 100 S -1). Experiments show that although this CWS is very suitable for long
